Winding 50 miles through the heart of Glacier National Park, Going-to-the-Sun Road is more than just a scenic drive—it’s a marvel of early 20th-century engineering, carved into some of the most rugged and remote terrain in North America. Its construction was a monumental effort that combined vision, innovation, and sheer determination.
The Vision Behind the Road
In the early 1900s, Glacier National Park was still largely inaccessible to the average visitor. While railroads brought tourists to the park’s edges, the interior remained the domain of horseback riders and hardy hikers. Park officials and tourism advocates saw the need for a road that would allow more people to experience the park’s alpine beauty.
The idea for a trans-mountain road was first proposed in 1917. The goal was to create a route that would connect the east and west sides of the park, crossing the Continental Divide at Logan Pass. But the terrain was steep, unstable, and often snow-covered well into summer. Building a road here would be no small task.
Planning and Design
The National Park Service, working with the Bureau of Public Roads (now the Federal Highway Administration), began serious planning in the 1920s. The design had to balance functionality, safety, and aesthetics. Engineers wanted the road to blend with the landscape, not dominate it.
To achieve this, they used a technique called “rustic design”, which emphasized natural materials and minimal visual impact. Stone retaining walls were built from local rock, and the road was carefully aligned to follow the contours of the mountains.
Construction Begins
Construction officially began in 1921, starting from both the east and west sides of the park. Crews faced extreme challenges:
- Steep cliffs and unstable rock required careful blasting and hand-finishing.
- Avalanches and rockslides were constant threats, especially near Logan Pass.
- Short working seasons—often just three to four months—due to snow and weather.
- Remote conditions meant that workers had to live in temporary camps and haul materials long distances.
Despite these obstacles, progress continued steadily. The most difficult section, known as the “Big Drift”, near Logan Pass, required extensive excavation and the construction of snow sheds and retaining walls.
The Final Push
The two halves of the road met in 1932, and Going-to-the-Sun Road was officially opened to the public on July 15, 1933. The final cost was around $2 million, a significant sum during the Great Depression.
The road was named after Going-to-the-Sun Mountain, a prominent peak visible from the eastern side of the park. The name itself is rooted in Blackfeet legend, adding cultural depth to the route’s identity.
A Lasting Legacy
Going-to-the-Sun Road was the first road in the world to be designated a National Historic Civil Engineering Landmark. It remains a symbol of what can be achieved when engineering meets environmental stewardship.
Today, the road is still maintained with great care. Due to its elevation and exposure, it requires constant upkeep, including snow removal that can take up to ten weeks each spring. Despite the challenges, it continues to offer millions of visitors a chance to experience Glacier’s alpine heart.
